Calendar Default Week View Change

Tanu Shree,

You can go to user profile and update the "First day of the weelk"


To automate it: Crete SQL script - Trigger

-- PART 1: GLOBAL UPDATE FOR EXISTING USERS
-- Applies the default TimeZone (MST) and DateTimeFormat (English - Canada) to all current users with a Contact.

UPDATE "SysAdminUnit" 
SET "DateTimeFormatId" = '6ebc31fa-ee6c-48e9-81bf-8003ac03b019'::uuid, 
    "WeekFirstDayId" = 'b42f7658-b2a1-4139-8595-1ee319cbfb8a'::uuid,
    "TimeZoneId" = 'Mountain Standard Time' 
WHERE "ContactId" IS NOT NULL;

CREATE OR REPLACE FUNCTION fn_sysadminunit_set_defaults()
RETURNS TRIGGER AS $$
BEGIN
   -- Only apply to actual user records (which have a ContactId), ignoring roles/groups.
   IF NEW."ContactId" IS NOT NULL THEN
       NEW."DateTimeFormatId" := '6ebc31fa-ee6c-48e9-81bf-8003ac03b019'::uuid;
        --NEW."LanguageId" = '41c3fb27-9e5a-4a17-a0d7-f8fb7e00bab1'::uuid;
        NEW."WeekFirstDayId" = 'b42f7658-b2a1-4139-8595-1ee319cbfb8a'::uuid;
       NEW."TimeZoneId" := 'Mountain Standard Time';
   END IF;
   
   RETURN NEW;
END;
$$ LANGUAGE plpgsql;


DROP TRIGGER IF EXISTS trg_sysadminunit_set_defaults ON "SysAdminUnit";
CREATE TRIGGER trg_sysadminunit_set_defaults
BEFORE INSERT ON "SysAdminUnit"
FOR EACH ROW
EXECUTE FUNCTION fn_sysadminunit_set_defaults();

Thank You Bhoobalan Palanivelu for the response it worked.
